Welcome

I am currently working as a PostDoc researcher at KAUST.  My main research area is parallel scientific computing.

I have expertise on:

  • data partitioning and task mapping/scheduling for exascale applications
  • locality aware partitioning and scheduling of irregular applications
  • parallel programming (on IBM BlueGene/P,Q and other parallel systems)
  • cache-aware methods and programming for scientific computational kernels
